I heard this live at the time and was most touched by his gesture, especially given that the track he dedicated to Clara was by The Orb and was the 20-minute long session version of 'A Huge Ever Pulsating Brain that Rules from the Centre of the Multiverse' - a truly momumental piece of music. It came from one of the Festive Fifty Countdown shows for (probably) 1989, give or take a year.
